For me, the largest part of my gripe about more and more sports moving to streaming is its the PITA of switching between the apps on SmartCast and my regular TV option(s) when trying to watch different games - which there are many - on Saturdays.
Watching the games on an app means taking the time for the TV to switch into SC mode, then find the app to start it, then find the game if it doesn't immediately pop up. Game on app either goes to commercial or halftime, and I want to check the score/action on a D*/cable game and I have to switch out of SC mode. Want to go back to the app game and need to re-wait for SC mode to load, re-find the app, re-start the app and re-find the game.
Such a f*ing hassle just to watch some football on a Saturday afternoon/evening.
